This function will provide an observed data log likelihood based on the
This function will take in information from global, but
no global variables will be updated by this function.
This function also don't take care the numerical issues, so the return value may be inaccurate sometimes.
An observed data log likelihood will be returned.
This value can quickly compare with the log likelihood computed inside
em.onestep. Small difference is allowed, but
large difference indicates bugs of code or illness of data.
